I have a Philips, Model # 43PP920217,, serial # 77384866, rear projection TV that has lost all focus, colors red, green ghost each other and create distorted picture. The center of the screen is worse, the picture gets warped, towards the sides its less noticeable. This problem has existed for the last year and we have not been able to find a repair shop nearby that will fix it without asking for over $900. I was told a year ago on the phone that to fix the problems I would need to change the lamps or bulbs, If I was lucky by just changing one of them I could solve the problem if not I would need to buy all three of them. But buying all three bulbs red, green, blue would be more expensive than buying a new TV,

If anyone has the same problem ? Have you been given a similar answer ?

replace the convergence ic. the IC# is STK392-120, replace this two ic at the same time. then put some silicon grease on the back of the IC for better heat transfer. some will work on replacing just 1 IC but I would recommend to replace both per philips advise. hope this help. regards, cebuwano.

If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. Please note that there are potentally dangerous hogh voltages present inside hte set even when unplugged.

You will have to go into Service Menu to realine convergences and What was the STKs numbers you replaced/ and did you go with same part number?I think i have service code for this set will have to look thur my files.

You need to replace both convergence ICs they are STK392-120 you will also need about four 6.8 ohm 1 watt resistors. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures. here is the link.http://servicemanuals.vstore.ca/

Its a straight forward repair just take out the convergence ICs and solder in two new ones. takes about an hour from beginning to end. just apply heat sink compound on the new ICs before installing them. And in that model check the resistors right next to the ICs as 1 or 2 of them often burn open when the ICs go out. Let me know if you need any additional info. The ICs cost about 10.00 each you will ned two.

two STK392-120 convergence modules that usually cause the beeping. So I
changed them both again, but I also found two open 7.5 ohm resistors
are in the general area of the convergence modules, and I replaced them
as well. I also replace 1 swollen capacitor that was probably going to
blow in the future but not really a problem yet.http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htmhttp://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.htmlSony Convergencehttp://www.techlore.com/blog/entry/19694/Sony-Convergence-Repair-My-Sony-TV-has-a-distorted-picture-/http://www.techlore.com/article/19631/Sony-Convergence-Procedure/

A common problem with this model is the convergence IC's on the small signal module going bad and keeping the set from staying on due to protective shutdown circuits used. If that is your problem, the easiest fix would be to replace the module - Philips Part #313503710091, about $200 or so, or have a technican replace both IC's Stk392-120, Philips Part #932212344682 about $45.00 each plus labor and service charge of course. Other parts could be bad, but this is likely what I would try first.
